GEORGE H. FORSYTH. OF CHICAfGO, ILLINOXS.

' nm'ranarrnnosi".

To all whom it may concern:

' Be it' known that l, GEORGE H. FonsY'rH, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, vhave invented certain new and useful 4lm rovements in Metal.Windows, of which the following is a specification.

My invention has for its general object to provide an improved metal-window construction wherein the sash may be adapted to variations inwidth or height of the casing, while at the same time preserving theproper engagement with the guides oi the casing. l show constructionswherein thls object may be accomplished through the provision ofcooperating surfaces on the sash and guide inclined to the plane of thesash, and also by means of an adjustable element of the sash, the latteralso permitting the edgewise insertion of the glass within the sash.

My invention, in an approved form, is illustrated in the accompanyingdrawings, Wherein,-

Figure 1 is an elevational view of a window sash showing one of thestiles thereof removed to facilitate the edgewise insertion of the glassinto the sash and illustrating the adjustability of one of the sashmembers. Fig. 2 is a top plan view, partly broken out and in section;Fig. 3 is a vertical sectional view on the line 3 3 of Fig. 1; Fig. 4 isa bottom plan view, partly broken out, of Fig. 1; Fig. 5 is a detailhorizontal sectional view illustrating the means for adjustably unitingthe detachable sash member tothe sash frame; Fig. 6 is a detailelevational view of the lower right hand corner of the sash showing thedetachable stile in the sash frame; Fig. 7 is a similar view of theupper right hand corner of the sash; Figs. 8 and 9 are detailcross-sectional views, on an enlarged scale, on the lines 8-8 and 9 9,res ectively, oi Fig. 7; and Figs. 10 to 19, inc usive are detailcross-sectional views illustrating the various forms ol inclined surfaceengagement between the sash and its casing guides.

In the drawings, 20 designates as an entiret the bars and 21 the stilesof the. sash. In t e forms herein shown, these members are hollow, beingmade of suitably bent strips of sheet metal. As shown at the upper endof Fig. 3 the two parallel face members of the stile are inwardly offsetat 22 to erlnit the olset portions to be overlapped by the ends of theparallel members oi the bar 20 Speeication of Letlici's Patent.. l

and riveted thereto, presentin Hush surlaces on both sides.- @ne of tiestiles 21 (that shown at the right in Fig. 1') is removably andadjustably secured to the top and bottom bars by the following means.The up er and lower offset portions 22 of said stie are s rovided withholes 23 and 24, respective y, occu in varyin transverse positions inthe st' dr sagid holes icing adapted to register with holes 25 and 26formed through the adjacent ends of the upper and lower bars,respectively, and receive screws or bolts '27 and 28 for uniting saidmembers.y An auxiliary means for adjustably securing the removable stile21 may consist of a pair of spring tongues 29 (Fi 5) secured to theinnervfaces of the paralle members of either 'o r both of the bars, saidton ues being inwardly offset to provide for t e insertion of the oHsetend portions 22 ofthe stile between the same and the inner faces of thebars, and having outwardly turned lips 29 adapted to enter in onevertical series of a number of correspondingly sha ed slots 30 formedthrough the offset portions 22 ci the stile. This auxiliary fasteningmeans may be applied to either or both of the bars and either or bothends of the stile, as desired.

'31 designates the glass, heldin place within the sash by strips 32,preferably also ol` -sheet metal and bent to the cross-sectional formindicated in Figs. 8 and 9, said strips having a hollow ortion 32aextending within the hollow sti es (for which purpose said stiles arebent to provide a rentrant portion 21, Figs. 8 and 9) and inwardlyinclined spring lips 32b clamping the glass. ln order to insure a closedjoint of the glass-holding strips at the corners formed by the removablestile, l miter the ends of the strip 32 carried by the removable stile,which provides an opening for the (passage therethrough of theadjacenten s of the horizontal strips carried by the upper and lowerbars, the Initered ends of the vertical strip 82 providing a closedjoint with the inclined sides of the removable strips in all positionsof adjustment, as more clearly shown in the cross-sectional view,Fig.l9.

From the foregoi that in assembling t e parts of vthe sash, before theremovable stile 21 is applied the glass 31 can be inserted edgewise intoposition, Fig. A1 showing said glass inserted through the open edge ofthe sash and nearly in fully entered position therein. The reit will beobserved,

movable stile 21 is then applied, the upper the casing as by a screw 40having a beveled and lower offset ends enterlng inside the adjacent endsof the bars and, in the case of the upper end as herein shown, fittingbetween the latter and l the spring tongues 29, as shown more.particularly 1n Figs. 5 and 7. In this operatlon the lips 29a enter oneof the series of slots 30, according to the intended width over all ofthe sash, in which position the hole 25 registers with one of the holes23, the holes 26 in the lower bar similarly registering with a pair ofholes 24, the exposed edOe of the glass being received to a greater orrless depth between the strips 32, as clearly shown in lgs. 8 and 9. Theinsertion of the screws 27 then effects the secure union of the parts,preventing accidental displacement of the removable stile.

At the lower end of the stiles I have shown the latter connected to theadjacent ends of the lower bar (see Fig. 3) by means of cleats 33riveted to the inner sides of the parallel face members of said bar andstiles this last described connection being optional with theconstruction shown at the upper end of the stile for uniting the sameparts.

It will be observed that the sash described and shown has merely stileswhich are transversely yieldable or elastic, for which purpose the solidtransverse portion of the upper bar is cut away where it overlies theupper ends of the stiles, as shown at 34 in Fig. 2, and similarly thesolid transverse member of the lower bar may be cut away at the ends toform V-shaped openings 35, the gussets thus formed (for the sake ofgiving a more nearly closed and finished appearance) being severed fromthe intermediate portion of the transverse member, as indicated at 35a,this construction permitting transverse yielding or elasticity at thelower ends of the Stiles.

l'In Figs. 1() to 1,9, inclusive, I have illustrated a variety of formswhich the coperating stiles and guides of the casing may assume, allwith the general purpose of permitting a certain extent of bodilywidthwise adjustment of the sash relatively to the opening whilemaintaining a proper it of the stiles in or upon theiiwguides. It willbe observed as a characteristic common to all of these forms that thesash -member and guide have cooperating surfaces that are inclined oroblique to the plane of the sash, this construction, where the sashmember is transversely yieldable orelastic, ermitting widthwisevariation of the sash re atively to the opening without destroying theproper engagement of the sash and guide. In all of the figures exceptFig. 19, 36 may be assumed to represent in cross-section a portion ofthe casing having a vertical uidegroove 37. In Fig. 10 I bend inward ythe projecting portion of one of the parallel face members of the stile,as shown at 38, said bent margin contacting a strip 39 secured to InFig. 12 both of the parallel face members of the stile are outwardlybent mar inally as shown at 41, and the strip 42 of iig. 11 is replacedby a strip 43 similar thereto except that it has an o lique innerbearing surface 43'$1 engaging one of said bent margins 41.

In Fig. 13 the groove 37 has both its side walls inclined in the samedirection (herein shown as parallel), as indicated at 44; and themarginal portions of the face members of the stile are similarly bent orinclined to iit said surface. f

In Fig. 14 the integral side wall of the groove is inclined inwardlyrelatively to the sash from its outer edge, as indicated at 45, thecoperating margin of the stile'being similarly bent to engage the same;while the inwardly turned margin of the other face member of the stileengages a wear strip 46 secured in place as by a screw or brad 47 andhaving a wear face 48 similarly but oppositely inclined to the wall 45.Said wearstrip 46 is backed by a finishing strip 49 extending flush withthe inner transverse wall of the casing opening.

Fig. 15 shows a stile having one straight face and its other faceoutwardly bent marginally to en age a correspondingly inclined surface50a o a removable strip 50.

Fig. 16 shows a casing provided with a substantially V-shaped groove,and the marginal portions of both face members of the stile inwardlyturned to engage the' inclined walls 51 of said V-groove.

In Fig. 17 I have shown the bottomwall of the groove provided with acentral projecting rib 52 having oppositely inclined surfaces 52a thatare engaged by inwardly and backwardly bent marginal portions 53 of thearallel face members of the stile, the latter aving also an outsidebearing against the parallel side walls of the groove.

Fig. 18 shows one side wall of the groove formed by a removable strip54, the inner face of said strip having a straight portion 54a engagingone of the parallel face members of the stile, and also an inclinedconvex portion 54b which is adapted to be engaged y an inwardlyturned'marginal ortion 55 of the other face member of the sti e.

The principle of the oblique or inclined transversely adjustablebearino' between the sash and the guide, as exempIiiied in Figs. 10 to18, inclusive, is capable of being carried out in constructions whereinthe acting guide,

classi instead of beinr formed as a groove, 4takes the form of a rib orprojection embraced by the parallel face members of the stile. Such aconstruction is shown in Fig. 19, wherein 56 designates a guide ribtriangular in crosssection secured to the wall 36 of the casing as by ascrewl57, the o lposite inclined sides or" said strip being slida yengaged by inwardly bent inclined marginal portions 58 of the stilemembers. In the forms shown in Figs. 10 to 18, inclusive, wherein thesash guide consists of .a roove in the casing, the parallel face memersof the stile may possess a transverse elasticity normally tending tospread said members beyond the width of the groove; in which case saidmembers, when engaged in the groove, are under a greater or less degreeoi compression, thus insuring a dust-proof and rattle-proof iit. At thesame time the.

provision of the inclined engaging surfaces combined with the elasticityof the sash member enables a given sash to fit and operate in windowopenings of somewhat vary ing widths. On the other hand, Where the sashmember may not possess transverse elasticity, as when made solid, thesame adaptability of the sash to window openings of somewhat varyingwidths is secured by the detachable stri s which may, after the sash hasbeen intro uced, be applied so as to produce an o erative fit againstthat side of the sash whic they engage. In the case of the constructionshown .in Fig. 14 the inner strip 46 may be adjusted within certainlimits Without disturbing the position of the main confining strip 49.

The constructions hereinabove described may lend themselves to a stillfurther advantage in respect to the manner of inserting the sash in thecasing where the total width of the sash is less than the distancebetween the bottoms of the grooves by a distance equal to or greaterthan the depth of one of the grooves, in which case, by suliicientlyexpanding or contracting the stile on one side it may be inserted intoone of the grooves until contacting the-bottom of the latter, which willallow the outer margin of the other stile to enter the mouth of itscoperating groove, the sash being then moved widthwise of its groove.Such a construction is illustrated in Figs. 15 and 16.

I do not limit the invention to the particular forms and constructionsshown and described, as the same may obviously be varied to aconsiderable extent without departing from the principle of theinvention or sacrificing any of the advantages thereof. f Y
